IDA查询和修改问题，遇到的难题，不忙的大神帮看看！我需要查找到并且修改，在查找这里遇到问题了，需要修改的文件是C语言编译生成的Liunx文件！生成文件有参考源码但是不一定完全一致！
先粘贴源码

我想修改的部分
[C++] 纯文本查看 复制代码 case Cmd::CREATE_SEPT_PARA:
{
BYTE bState = 1; //先初始化成成功状态
if (charbase.septid == 0) // 家族ID大于0表示加入家族
{
time_t cur_time = time(NULL);
if ((cur_time - charbase.levelsept) < 24*60*60)
{
//离开时间不足24小时
bState = 0;
Channel::sendSys(this, Cmd::INFO_TYPE_FAIL,
"离开家族后24小时, 才能再建立家族");
}
24*60*60改成60
需求解释完毕！

需要找到对应的 case Cmd::CREATE_SEPT_PARA:
if ((cur_time - charbase.levelsept) < 24*60*60)修改 60 遇到的问题在这里无法找到 对应的位置请问用什么方法可以找到！转换16进制查询不到！
谢谢了！
